Honestly she sounds very normal to me! My son has been through similar behaviours at different times.

I don't understand why she must have to door shut. Imagine yourself as a little girl. In a room all alone in the dark with the door shut...... of course she is going to bang on the door and cry. She is 'shut in' The night light thing - it sounds like she is already scared of the dark. And who cares if it means that she has a night light. I own a paortable battery operated disney light that we use when we stay somewhere else. owrks great, as DS can see in his room and knows where he is.

I understand that DH needs his sleep, but with some very simple things she may begin to sleep better.

Good luck.
